2023 Audi RS 6 Avant 4.0 TFSI Quattro

Offered from Audi’s modern RS lineage, this 2023 Audi RS 6 Avant 4.0 TFSI Quattro presents the rare, high-performance wagon formula that helped reignite the “super estate” segment in the U.S. market. The RS 6 name traces back to Audi’s original RS 6 of the early 2000s, an icon for its twin-turbo V8 power and everyday usability, while today’s RS 6 Avant continues that ethos with contemporary technology, elevated luxury, and formidable real-world pace. Finished in Nardo Gray over a Black interior with Express Red stitching, this example shows 24,350 miles and is offered by an owner who is selling after purchasing another vehicle.

Power comes from Audi’s 4.0-liter twin-turbocharged V8 paired with a hybrid assist system and routed through quattro all-wheel drive and an automatic transmission, delivering the signature RS blend of traction, cross-country refinement, and supercar-level acceleration. Key technical highlights include an electro-mechanical limited-slip differential, dual stainless-steel exhaust, regenerative 4-wheel disc brakes with ABS, and an auto-leveling suspension system; this car is further specified with Dynamic Ride Control suspension for enhanced body control. EPA estimates are 14 mpg city and 21 mpg highway, and the original retail price when new was $132,970 (including destination and gas guzzler tax).

Factory equipment and options from the window sticker emphasize both performance and high specification: Black Optic Package, Red RS Design Package, red brake calipers, 22-inch Titanium 5-V-spoke Trapezoid-design wheels, Sport Exhaust, Audi Side Assist, and the Bang & Olufsen Advanced Sound System with 3D sound. Additional notable features include laser-supplement LED headlights, surround-view camera system, Audi pre sense front, power liftgate, HomeLink, Audi connect services, and a 16-speaker audio layout. The owner reports no modifications and notes the vehicle remains under factory or CPO warranty; according to the seller, recent maintenance included an inspection with brakes checked, a fender liner repair/replacement, safety inspection, tire service, and replacement of two tires on 08/06/2024 and the remaining two on 06/19/2025.
